The technology of bi-metal casting is considered one of the promising technologies in the field of casting industry. The main applications of bimetal casting are dynamic loads and intensive abrasive wear. Understanding of the process and its dynamics are the main tool for successful bi-metal casting products. This review aims to focus on the past and present techniques of bi-metal casting in order to facilitate its production processing and improve its products performances. The advantages and
more » ... The advantages and limitations of liquid-solid and liquid-liquid bi-metal casting configurations are shown. New trends in bi-metal casting are classified into two categories; the first one depends on the production processing, such as continuous casting and electroslag heating processes while the second one depends on product applications, like corrosion resist, heat resist and bearing layered castings. In this review, the significance of factors affects the process of bi-metal casting to achieve high quality products is presented. Bi-metal casting interface is considered one of the most important factors that achieve a stronger bond between the pair of metals. The current review will handle the present and future status of the bi-metal casting, along with their applications in the manufacturing of certain metal products. The technical and economic environment, which is prompting the improvement of this technology will be clarified. Although new trends and developments of bi-metal casting reported, there are still many future challenges for developing bi-metal casting industry in order to increase bi-metal quality, its performance and decrease its production cost.
